Embodiment Construction

[0033] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0034] see image 3 , is a schematic diagram of the RoT control flow provided by the embodiment of the present invention. As shown in the figure, the flow may include:

[0035] Step 301, NodeB according to the RoT threshold configured by the system (expressed as ROT THD , the same below), and the power of other channels with the same time slot as the scheduled E-PUCH, determine the RoT threshold of the scheduled E-PUCH in this time slot (expressed as ROT E-PUCH , the same below).

[0036] Step 302, NodeB uses SNPL to estimate the possible uplink interference caused by sending E-DCH, according to the interference threshold ROT of the system E-PUCH Determine the maximum allowable accepted power P RoT , get a power license 1 for Among them, P RoT The calculation formula is:

[0037] P RoT = ...

Abstract

The invention discloses a co-time-slot scheduling method and device of E-PUCH and other channels. The co-time-slot scheduling method comprises the steps of: increasing the RoT threshold relative to the background noise according to the receiving power of system configuration, and determining the RoT threshold for scheduling the E-PUCH in the time slot according to the power for scheduling other channels in the time slot same as the E-PUCH; determining the allowed maximum receiving power according to the determined RoT threshold, and determining the first power permission according to the allowed maximum receiving power; determining a second power permission according to the latest reported power allowance; and distributing wireless resources according to a smaller value of the first power permission and the second power permission. When being used for scheduling the E-PUCH and other channels in the time slot same as the E-PUCH, the co-time-slot scheduling method and device can improve the system performance.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a scheduling method and device when an E-PUCH shares a time slot with other channels. Background technique [0002] In the HSUPA (High Speed ​​Uplink Packet Access, High Speed ​​Uplink Packet Access) system, the typical time slot configuration of the H carrier is as follows figure 1 shown. [0003] Usually in the following four cases, there will be a time slot configuration in which E-PUCH (E-DCH Physical Uplink Channel, enhanced uplink physical channel) shares time slots with other channels: [0004] (1) The DPCH (Dedicated Physical Channel, Dedicated Physical Channel) of TS1 of the current carrier is relatively idle, and some code channel resources of TS1 are configured as E-PUCH channels, then the E-PUCH channel and PRACH (Physical Random Access Channel, physical random Access Channel) / HS-SICH (High Speed ​​Shared Information Channel, High Speed ​​Shar...
